DTC detecting condition |
|---|---|---|
| P0111 | IAT SENSOR 1 B1 (Intake air temperature sensor 1 circuit range/performance bank 1) |
The comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor 1, ECT sensor 1, FTT sensor, and EOT sensor) shows that the voltage signal of the IAT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state. |
POSSIBLE CAUSE
- Harness or connectors (High or low resistance in the IAT sensor circuit)
- Mass air flow sensor (bank 1) (IAT sensor 1)
FAIL-SAFE
